    stream As Stream,
    largestEdgeLength As Integer,
    pageNumbers As IEnumerable(Of Integer)
)

Parameters

Name	Type	Description
stream	Stream	A stream to which the TIFF image should be written.
largestEdgeLength	Int32	A length of the image’s largest dimension, in pixels.
pageNumbers	IEnumerable<Int32>	A list of page numbers.

Note

Set the RenderingEngine property to Skia to enable this method on Azure Web Apps, Linux, or Mac OS. To use the Skia rendering engine, add a reference to the DevExpress.Pdf.SkiaRenderer package or the DevExpress.Pdf.SkiaRenderer.v21.2 library reference with the SkiaSharp package (v1.68 if you use .NET Framework 4.5 and v2.80 for .NET Standard).

The following example shows how to convert pages to a multi-page TIFF image.

C#

using DevExpress.Pdf;

static void Main(string[] args)
{

  int largestEdgeLength = 1000;
  int[] pageNumbers = new int[] { 1, 3, 5 };

  using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
  {
    // Load a document.
    processor.LoadDocument("..\\..\\Document.pdf");
    using (var stream = new FileStream("..\\..\\Image.tiff", FileMode.CreateNew, FileAccess.Write))
    {
      // Export pages to a multi-page tiff image.
      processor.CreateTiff(stream, largestEdgeLength, pageNumbers);
    }
  }
}

VB.NET

Imports DevExpress.Pdf

Private Shared Sub Main(ByVal args As String())
    Dim largestEdgeLength As Integer = 1000
    Dim pageNumbers As Integer() = New Integer() {1, 3, 5}

    Using processor As PdfDocumentProcessor = New PdfDocumentProcessor()
        processor.LoadDocument("..\..\Document.pdf")
        processor.CreateTiff("..\..\Image.tiff", largestEdgeLength, pageNumbers)
    End Using
End Sub
